This Squat Lobster is
on the defensive, holding its claws up toward the
perceived threat. This view shows one way to tell that
the name "Squat Lobster" is a misnomer-- the
lack of a tail, which all lobsters have, but crabs don't.
The "lobster" part of its common name is
probably due to the similarities in the long chelipeds
(arms) to the true lobsters.

For divers: the photos shown here are of a few common
commensals found on crinoids, but there are many other
creatures that may serve as hosts to small but
fascinating animals. Try looking closely at sea fans,
starfish, sea cucumbers, or sea urchins the next time you
dive-- but look very, very closely, or you'll likely be
fooled by their disguises!
